Hello Sandeep, thank you for the video! The inverse relationship (negative slope) of the H v Q curve for the backward vane impeller curve is a result of the negative term (& beta2 < 90) in the Euler equation. However, why is the "backward shape" resulting into this behavior (how is the blade shape affecting the H vs Q relationship?). In other words, how would one understand this relationship between the curve & the shape of the impeller blade practically without looking at the equation? Thanks in advance!
You are right. That relationships is mathematically possible. Since trimming change shape of impeller (increase specific speed). Above relationships cannot be utilized. In this case industry apply Q=f(D), H=f(D2), P=f(D3).

Is lacture ko dekhke lagend SK som sir ki yad a gai. What an amazing lacture sir 🙏🏻
Your videos are so special,
I usually take reference of it in my videos. !!
Share your videos !
Sir please make a video on selection of pumps for interviews🙏🏻🙏🏻
Sir recently I was asked whether cavitation occurs in a Reciprocating pump. Can you please enlighten on this
Sir ji app bhaut accha padate ho
Sir please make a video on heat exchanger. Thank you sir
Please make part 2
For Interview questions and answers

Sir reciprocating compressor ka bhi video banaiye pls
How can i add english subtitles?!! Thanks for your efforts.
is this for chemical eng??
Sir heat exchanger par video bnao
I ist viewers.
Sir video jaldi jaldi lao please
Q is directly proportional to D
Thanks a lot
Sir ji petroleum refining engineering ki videos bna do
Sir, mechanical seal ka 3rd part ayega ki nei?. ham intijar kinye hai...
Seal flushing plan pe video banayenge
@@SandeepAcademy9 thik hai jaldi banaye, me kharagpur se hnu....
H is directly proportional to D2
motors constant RPM pe kam kartehe?
Yes
@@SandeepAcademy9 hello sir is there any whatsapp group or telegram group that i can contact you? Im preparing for BARC interview
Direction of rotation of centrifugal pump is anti cock wise not clock wise.
No it is not like that. It can be clockwise as well as anti-clockwise
isn't it H=f(N2,D2)
Q=f(N,D3)
P=f(N3,D5)

@@SandeepAcademy9 thanks a lot.
Sir you're taking too many gaps in explaining.
